Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Experimental result using standard methods of analysis
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Principles of method if other than guideline:
- The boiling point of a liquid is the temperature at which that liquid is converted to a gaseous state. It can be defined as the temperature at which the vapour pressure of the liquid becomes equal to the pressure at the surface of the liquid.
- GLP compliance:
- no
- Type of method:
- method according to Siwoloboff
- Boiling pt.:
- 234.3 °C
- Atm. press.:
- 967 hPa
- Decomposition:
- no
- Remarks on result:
- other: experimental result
- Conclusions:
- The boiling point determination of3,7-dimethylocta-2,6-dienenitrile (CAS No. 5146-66-7) was done following OECD Guideline 103 and according to the method of Siwoloboff. The test was conducted in replicates and mean boiling point was found to be 234.3 °C at 967.2 hPa.
- Executive summary:
In an experiment conducted by SSS (Europe) AB,the boiling point determination of 3,7-dimethylocta-2,6-dienenitrile (CAS No. 5146-66-7) was done following OECD Guideline 103 and according to the method of Siwoloboff. The test was conducted in replicates and mean boiling point was found to be 234.3 °C at 967.2 hPa.

Description of key information
In an experiment conducted by SSS (Europe) AB,the boiling point determination of 3,7-dimethylocta-2,6-dienenitrile (CAS No. 5146-66-7) was done following OECD Guideline 103 and according to the method of Siwoloboff. The test was conducted in replicates and mean boiling point was found to be 234.3 °C at 967.2 hPa.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 234.3 °C
Additional information
In an experiment conducted by SSS (Europe) AB,the boiling point determination of3,7-dimethylocta-2,6-dienenitrile (CAS No. 5146-66-7) was done following OECD Guideline 103 and according to the method of Siwoloboff. The test was conducted in replicates and mean boiling point was found to be 234.3 °C at 967.2 hPa.
Other supporting studies from reliable sources such as authoritative database and review article also suggests that the boiling of chemical is between the range of 234 degree C to 260 degree C.
As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of boilingg point as 234.3 degree celcius thus considered as key study for the chemical safety assessment.
